The headers already sent message with ob_gzhandler enabled problem is solved.

However, the lynx -head problem is still there.

both problems are fixed in CVS

I've just found out what the problem is, and it's kind of weird:
With ob_gzhandler enabled (from php.ini or with ob_start("ob_gzhandler") in the .php) 
each readfile() makes the "Cannot add header information - headers already sent" error 
message appear.
This doesn't happen with output buffering enabled and no ob_gzhandler, it only happens 
with ob_gzhandler enabled.

Also tried to replace readfile with fpassthru(fopen()) but got the same result.

Hope this helps you fix the problem.

If you have any questions feel free to ask, I've been experimenting quite a lot.

Tried the php4-200102020545 snapshot and I still get the

httpd: PHP Warning:  Cannot add header information - headers already sent in Unknown 
on line 0

error message when enabling output_handler = ob_gzhandler.
This probably still causes a memory leak.

Found another interesting thing: when trying to see the headers of a ob_gzhandler 
compressed page with lynx, I get the following lynx error message:

Can't access startfile http://localhost/test.php

That's using lynx -head -source http://localhost/test.php. Seems lynx sees something 
which it doesn't like. With ob_gzhandler disabled, I get the normal http headers when 
invoking that lynx command.
